Vacuum 2 stage pump with mist eliminator, Alcatel 2012. Not exactly portable
Since Alcatel didn't exist for years now, that has to be second hand. I have one like that (bit bigger, Alcatel 2033) so I'll mention a caution, just in case you didn't know.
First time you try running it, do it outside. Because those oil mist filters use a cartridge that can become oil saturated, then air can't go through it. To prevent the pump from blowing itself up with overpressure, the mist filter has a spring on the cartridge, so it pops up and lets air go around it if it's blocked. Result: when I turned mine on to test the motor rotation (3 phase) the pump filled up the room with oil fog in about 2 seconds flat before I could turn it off. Oil last used in a university chem lab environment. I ran for the door holding my breath.
I couldn't find a source for replacement filters, so did a bad thing - soaked it in solvent, dried it, resoaked, etc. After this treatment it works, but of course will forever back-stream solvent into the pump. For my use, that doesn't matter. Hopefully.
